Fetch-22

GET and POST JSON with less code and more convention.

First, instantiate it:

const fetch = window.fetch.bind(window) // require('node-fetch')
const baseUrl = 'http://localhost:9988'
const fetch22 = new Fetch22({ baseUrl, fetch })

Second, use it:

// GET
const obj = await fetch22.get('/foo')

// POST
await fetch22.post('/foo', { bar: 'zap' })

get throws an error when the response isn't 200. post throws an error when the response isn't 201. The error contains the response body as text as well as the actual status code.

That's what we need 22% of the time. For the remaining 78% of cases, don't use Fetch-22.
